The overheating protection methodfor user equipment can be applied to the user equipment. As shown inFIG. 1A, the overheating protection method for user equipment includesthe following steps 101-103.

In step 101, a first signaling is sent to a base station, the firstsignaling carrying indication information indicating that the userequipment has a capability of reporting a temporary capability of theuser equipment.

In an embodiment, the first signaling may be other parameterOther-Parameters-v14xy signaling in a UE-EUTRA-Capability signaling ofthe UE for reporting network capabilities supported by the UE. By addingtemporary UE capability indication information tempUECapability-r14 inthe Other-Parameters-v14xy signaling, to indicate that the userequipment has a capability of reporting a temporary capability of theuser equipment. In an embodiment, the temporary capability of the userequipment can be understood as a network capability temporarilysupported by the UE when it is overheated. The first signaling can bethe following codes as reference:

Other-Parameters-v14xy ::= SEQUENCE{ bwPrefInd-r14 ENUMERATED{supported} OPTIONAL tempUECapability-r14 ENUMERATED {supported}OPTIONAL }

In step 102, it is monitored whether the base station returns a secondsignaling in response to the first signaling within a preset timeperiod.

In an embodiment, the preset time period may be determined by a presettimer with a timing length being the preset time period. The presettimer is started after the request message is sent, and it is monitoredwhether a response message is received before the preset timer expires.

In an embodiment, the second signaling may be one of other configurationOtherConfig signaling in the Radio Resource Control (RRC) connectionreconfiguration RRCConnectionReconfiguration signaling, for example, maybe named as temporary UE capability configuration signalingtempUECapabilityConfig-r14. Through the tempUECapabilityConfig-r14signaling, the user equipment can report a temporary UE capability whenan overheating problem occurs. That is, through thetempUECapabilityConfig-r14 signaling, the user equipment can beindicated that the base station has an overheating solving capabilityfor the user equipment.

In an embodiment, the base station may further carry an overheatingprevention timer and a time length overheatingIndicationTimer-r14 of thetimer in the tempUECapabilityConfig-r14 signaling. Upon receiving thesecond signaling, the user equipment can parse the second signaling toobtain the time period length of the overheating prevention timer, senda third signaling for adjusting wireless link configuration whenoverheating, and after that, start the overheating prevention timer todetermine a sending time for resending a signaling for adjustingwireless link configuration. For example, if the user equipment is stilloverheated after the timer expires, the time when the timer expires maybe determined as a sending time for resending a signaling for adjustingwireless link configuration, to avoid that the user equipment sends asignaling for adjusting wireless link configuration too frequently. Thesecond signaling can be the following codes for reference:
